Question

A ball is thrown vertically upwards. Which of the following plots represents the speed-time graph of the ball during its flight if the air resistance is not ignored

The correct answer is:

For upward motion
Effective acceleration $equals negative open parentheses g plus a close parentheses$
And for downward motion
Effective acceleration $equals left parenthesis g minus a right parenthesis$
But both are constants. So the slope of speed-time graph will be constant
